| Abstract: | Based on the conceptual framework of internal models of the deterministic signal and disturbance, two types of composite state-space model, of the mixture of the visual evoked potential (VEP) with residual Electro-encephalogram (EEG) were derived. Based on the two time-domain parametric models, the adaptive estimation of the VEP signal was realized by using the iterative solution of extended Kalman filter. The filtering performance using each model was then compared and analyzed through extensive clinical applications. |
